Chemical Structure
Description
The occurrence of 2-Phenyl-1h-1,3-benzodiazole-5-sulfonyl chloride hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Phenyl-1h-1,3-benzodiazole-5-sulfonyl chloride hydrochloride (CAS 27503-80-6) is a high-purity analytical reference standard with the molecular formula C13H9ClN2O2SHCl and a molecular weight of 329.19 g/mol.
2-Phenyl-1h-1,3-benzodiazole-5-sulfonyl chloride hydrochloride (C13H9ClN2O2SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Phenyl-1h-1,3-benzodiazole-5-sulfonyl chloride hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
